WebNov 1, 1999 · First, if we consider the enthalpy of decomposition of H 2 O 2 to occur via disproportionation, then we can use the value of −196.1 kJ/mol for that process. 39 Second, we need to consider the ... WebTherefore, the reaction must be specified for which this quantity applies. In this case, the enthalpy of 484 k J is released when 2 m o l of hydrogen gas react with 1 m o l of oxygen gas to form 2 m o l of gaseous water: 2 H X 2 ( g) + O X 2 ( g) 2 H X 2 O ( g) Δ H ∘ = − 484 k J. (By way of comparison, the corresponding value for liquid ...
